• CSIRO studies confirm presence of hydrogen, helium and associated gases in multiple drillholes
• Helium detected in a sandstone drillhole near the Talga Fault, indicating potential traps and source rocks
• Wanna Syncline identified as a prime target for further seismic acquisition and drilling

Constellation Resources Limited has received preliminary results from testing conducted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) on crushed rock and fluid inclusion analysis across its Edmund-Collier Natural Hydrogen Project. The analysis has confirmed the presence of hydrogen, helium and associated gases, including methane and ethane, in multiple drillholes within the project area. Importantly, helium has been detected in a sandstone drillhole sample located near the Talga Fault, which is one of two basement tapping faults that extend along the north and south boundaries of the Wanna Syncline. The Wanna Syncline is interpreted to have preserved traps and source-rocks sufficiently buried, with overlying seals, for hydrogen and associated gases to be either retained within shales or within overlying reservoirs. The company is highly encouraged by the results, which support the development of the Edmund-Collier as a first-of-its-kind opportunity in Western Australia to explore for natural hydrogen and helium across a large, underexplored basin. The company is now well advanced to undertake surface-gas sampling programs and further seismic acquisition and drilling in the Wanna Syncline area to define drill targets.

The key aim for work programs underway within the Company's wider Western Australian NatH2 land portfolio is to confirm prospectivity and to define drill targets. The company has been rewarded preferred candidate status for nine Special Prospecting Authority -Acreage Option 'SPA-AO' permits by the Department of Mines, Petroleum and Exploration, which allows the company to undertake low-cost, high-value work programs.
